That's not that bad of a deal.. 9 quarts M1 at AutoZone is 9*$5.29= $47.61, *1.0865 Westminster tax= $51.73 for the oil. Add another $8 for the filter, and you're at $60.. so for $15 you don't have to get your hands dirty, or drive to Auto Zone, and then later drive back to dump the old oil.

But you don't get to be the one to install the new filter and retorque the drain plug, and you don't get to make sure all the drips are wiped clean. And that's probably why most of us prefer to do it ourselves..
